Tableau is a data visualization software application that allows you to easily create and share interactive charts, graphs, and maps. While the free version of this tool, Tableau Public, has offered wonderful opportunities for generating and publishing data visualizations, there are file size and format limits that make it difficult for some [...]
Visualizing spatial data can be challenging. Specialized software tools like ArcGIS produce excellent results, but often seem complex for relatively simple tasks. Several online tools have emerged recently that provide relatively easy alternatives for the display of spatial data. In this post, we examine Google Fusion Tables, which combines visualizations, including spatial visualizations, with a [...]
Overview
ArcGIS Online is a service that allows for storage and sharing of spatial data and maps. In contrast to many other web based GIS services, ArcGIS Online accepts geocoded text-based data and shapefiles, which allows users to share and present work built in ArcGIS Desktop.

Visualizing spatial data can be challenging to learn. Specialized software tools like ArcGIS produce excellent results, but often seem complex for relatively simple tasks. Several online tools have emerged recently and provide relatively easy alternatives for the display of spatial data. In this ongoing series of alternatives, we review Tableau Public 7 in detail.

The Census Bureau’s American Community Survey provides a continuous measure of the community demographics in the US. A new extension provided by the Department of Geography and Geoinformation Science at Geroge Mason University enhances the mapping of ACS by data by allowing researchers to visualize both survey estimates while revealing the level of [...]
One of the limitations of computer mapping technology is that it is new. There is little historical imagery and data available as a result, although this has started to change. The integration of paper and imaged maps into computer mapping technology is possible, and this tutorial will walk through the process of georeferencing.

What’s new in ArcGIS 10?
By Ryan Denniston On October 12, 2011 · Leave a Comment · In Data Visualization, GIS, spatial humanities
Would you like to add aerial photography or a topographic map underneath map layers for visual appeal or context? With ArcGIS 10, you can add a basemap to your map project.
A basemap is a link to an online imagery data source. You must be connected to the Internet in order to see a [...]
Introduction
ArcGIS 10 makes it easy to manage and visualize time-series data to identify trends and create compelling visualizations. Creating a visualization of time-series data requires only a few additional steps beyond those needed to produce any map.
Step 1: Data Formatting
Time-series data contains records, each of which is specific to both an individual [...]
